Hi, i´m user of a wonderfull Carl Martin Quattro and i like too much, but i have a dude, there is little diference between drive 1 and drive 2, are there any mod for get mor drive o volume on Drive 2, them it will be the most perfect pedal board on the world.Anyway i´m really happy fot got it!thanks so much!

Hi...it is the same drive, with different potmeters attached, like the Plexitone.Making it more dirty will change the character, and it will affect both channels as they share the same clipcircuit.We can change it, but you will have to mail us at info@carlmartin.com for the details.
